Matching a deep vee Alumacraft Competitor 175 Sport 2011 against a modified vee Alumacraft Dominator 165 Sport 2007 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Alumacraft Competitor 175 Sport 2011 at 17,7 ft versus Alumacraft Dominator 165 Sport 2007 at 16,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Competitor 175 Sport 2011 tips the scales at 1 285 lbs — 1 160 lbs more than the Alumacraft Dominator 165 Sport 2007 at 125 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 150 hp, the Alumacraft Competitor 175 Sport 2011 has a 60-hp advantage over the Alumacraft Dominator 165 Sport 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Alumacraft Competitor 175 Sport 2011 carries 38 gallons versus 22 gallons in the Alumacraft Dominator 165 Sport 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Dominator 165 Sport 2007 comes in at 1 lbs per hp versus 9 lbs per hp for the Alumacraft Competitor 175 Sport 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
